A day in Jason's life. Not just an ordinary day, but a special lucky day. And Jason feels in his bones that something very nice will happen to him. It does. He finds a bit of glass; a boomerang which almost breaks his neighbor's window, but doesn't; and his father helps him start his very own museum. A sunny story which rests on the little adventures which are recognizable to a child, and which, in reality, give excitement to his life.
